  • Tectonic Influences on the Spatial and Temporal Evolution of the Walker Lane: an Incipient Transform Fault Along the Evolving Pacific – North American Plate Boundary
    Arizona Geological Society Digest 22 2008 Tectonic influences on the spatial and temporal evolution of the Walker Lane: An incipient transform fault along the evolving Pacific – North American plate boundary James E. Faulds and Christopher D. Henry Nevada Bureau of Mines and Geology, University of Nevada, Reno, Nevada, 89557, USA ABSTRACT Since ~30 Ma, western North America has been evolving from an Andean type mar- gin to a dextral transform boundary. Transform growth has been marked by retreat of magmatic arcs, gravitational collapse of orogenic highlands, and periodic inland steps of the San Andreas fault system. In the western Great Basin, a system of dextral faults, known as the Walker Lane (WL) in the north and eastern California shear zone (ECSZ) in the south, currently accommodates ~20% of the Pacific – North America dextral motion. In contrast to the continuous 1100-km-long San Andreas system, discontinuous dextral faults with relatively short lengths (<10-250 km) characterize the WL-ECSZ. Cumulative dextral displacement across the WL-ECSZ generally decreases northward from ≥60 km in southern and east-central California, to ~25 km in northwest Nevada, to negligible in northeast California. GPS geodetic strain rates average ~10 mm/yr across the WL-ECSZ in the western Great Basin but are much less in the eastern WL near Las Vegas (<2 mm/ yr) and along the northwest terminus in northeast California (~2.5 mm/yr). The spatial and temporal evolution of the WL-ECSZ is closely linked to major plate boundary events along the San Andreas fault system. For example, the early Miocene elimination of microplates along the southern California coast, southward steps in the Rivera triple junction at 19-16 Ma and 13 Ma, and an increase in relative plate motions ~12 Ma collectively induced the first major episode of deformation in the WL-ECSZ, which began ~13 Ma along the N60°W-trending Las Vegas Valley shear zone.

It has occupied a criti- cal structural position in the western Cordillera since Mesozoic time. In the Cretaceous through early Tertiary, it stood just east and north of major fold and thrust belts and also marked the northern end of a broad, gently (~15o) north-plunging uplift (Kingman arch) that extended southeastward through much of central Arizona. Mesozoic and Paleozoic strata were stripped from the arch by northeast-flowing streams. Peraluminous 65 to 73 Ma granites were emplaced at depths of at least 10 km and exposed in the core of the arch by earliest Miocene time. Calc-alkaline magmatism swept northward through the northern Colorado River extensional corridor during early to middle Miocene time, beginning at ~22 Ma in the south and ~12 Ma in the north.

Determination of the areal distribution, geochronology, lithology, geochemistry, and internal stratigraphy of the TBS is important for its establishment as a reliable stratigraphic reference horizon for tectonic reconstructions of the extensional corridor during the middle Miocene.

  • Chapter 3 Affected Environment
    Chapter Three Chapter 3 Affected Environment 3.1 Introduction Chapter 3 describes environmental resources (e.g., hydrologic, biologic, and socioeconomic) of the Colorado River Basin that could be affected by the proposed federal action and the range of alternatives for implementing the proposed federal action described in Chapter 1 and Chapter 2, respectively. The extent to which each specific resource may be impacted is discussed in Chapter 4. Section 3.2 presents a general discussion of the geographic scope within which potential effects of the alternatives are analyzed, and describes each of the potentially affected Colorado River reaches and water service areas. Subsequent sections in this chapter describe specific resources that may be potentially affected, such as water deliveries, recreation and biologic resources. Each resource section contains a discussion of one or more specific issues identified for consideration through scoping, public review and comment, and internal review (Chapter 1, Table 1.5-1).
